380 Recently published Ornithological Works. 
Baron Snouckaert van Schauburgh’s ‘ Aves Neerlandicse/ 
which we hope to he able to notice in our next number. 
Dr. Van Oort’s memoir contains a list of all the known 
birds of Holland, 335 in number according to his reckoning, 
with remarks, especially on those represented in the Leyden 
Museum. Schlegel, who ruled that Museum so long and so 
worthily, adhered stedfastly to the old-fashioned plan of 
having all the specimens mounted. The natural con¬ 
sequence was that the shelves became crowded with a 
large series of birds, w T hich it was impossible for the 
Ornithologist of the present age to use. It has been left 
to his successors at Leyden to alter this inconvenient plan, 
and, if we understand rightly, Dr. Van Oort with the help 
of many friends is now hard at work on a “ collection of 
indigenous birds ” for purposes of comparison. 
We must not forget to mention that the Leyden Museum 
has lately received a very valuable addition by the bequest 
to it of the well-known collection of native birds of the late 
Baron van Wickevoort Crommelin. 
Following the recent inconvenient innovation, Dr. Van 
Oort commences his List of Netherland Birds at the 
bottom. After the name of each species he gives the 
number of specimens of it in the Leyden Museum, and 
particularizes special examples worthy of notice. He also 
gives the popular names in the language of Holland, which 
are more different from the ordinary English vernacular 
appellations than we should have expected. As regards 
nomenclature he is not a full-blown trinomialist, except in 
special cases, such as the Wagtails and Tits; but he allows 
“ homonyms/’ which are ugly, especially when the same name 
is repeated three times over. He has also adopted the 
perverse practice of not altering the termination of a specific 
term when the genus is changed—hence such barbarities as 
Porzana parvus , Porzana pusillus , and Totanus maculata. 
There is not, so far as we know, any canon of the Inter¬ 
national (or any other) Code w 7 hich sanctions this obvious 
violation of the Laws of grammar—laws which, to our 
minds, are of far greater importance than those of Priority.
